F-i-L....or FIL...funny you mention that. Young teams make young mistakes. A mature team would have had time plus a timeout to know exactly where it was. If this was USC or Oregon and not WSU whether it is PRice's WU or Doba or whoever, that goal line play gets reviewed or the refs at least stop the clock and talk it over. JUst like when WIcks scored against Cal, WU never gets the benefit of the doubt.
With that said, if the previous two plays the receiver runs out of bounds instead of tries to gain another 5 yards, and conversely, the next play where the WR runs out of bounds where it looks like he really had a chance to make a play and score, both young players mistakes. As far as who would have gone for it and who would have kicked it, conventional wisdom is you kick it and take your chance in OT. Your QB is hot. The otehr QB is marginal. Stop White, you stop Utah.
But I will say one play is moronic with a freshman QB at the helm in HAlliday. Match that up against the clock management against Cal in which WSU had a senior Connor Halliday running the show and instead of getting off another play he calls time out. Run the ball one more time and then call the time out. Why did Leach allow that to happen? Then he sends out a kicker who shanks an extra point.
See, every play and every close game can be equally scrutinized. Upper classmen do the things, the small things that win games.
